A search game taking account of attributes of searching resources

This article deals with a two‐person zero‐sum game called a search allocation game (SAG), in which a searcher and a target participate as players. The searcher distributes his searching resources in a search space to detect the target. The effect of resources lasts a certain period of time and extends to some areas at a distance from the resources' dropped points. On the other hand, the target moves around in the search space to evade the searcher. In the history of search games, there has been little research covering the durability and reachability of searching resources. This article proposes two linear programming formulations to solve the SAG with durable and reachable resources, and at the same time provide an optimal strategy of distributing searching resources for the searcher and an optimal moving strategy for the target. Using examples, we will analyze the influences of two attributes of resources on optimal strategies. © 2007 Wiley Periodicals, Inc. Naval Research Logistics 2008

An attacker‐defender model for analyzing the vulnerability of initial attack in wildfire suppression

Wildfire managers use initial attack (IA) to control wildfires before they grow large and become difficult to suppress. Although the majority of wildfire incidents are contained by IA, the small percentage of fires that escape IA causes most of the damage. Therefore, planning a successful IA is very important. In this article, we study the vulnerability of IA in wildfire suppression using an attacker‐defender Stackelberg model. The attacker's objective is to coordinate the simultaneous ignition of fires at various points in a landscape to maximize the number of fires that cannot be contained by IA. The defender's objective is to optimally dispatch suppression resources from multiple fire stations located across the landscape to minimize the number of wildfires not contained by IA. We use a decomposition algorithm to solve the model and apply the model on a test case landscape. We also investigate the impact of delay in the response, the fire growth rate, the amount of suppression resources, and the locations of fire stations on the success of IA.     

C~3I系统试验评估方法

C3I系统试验评估是C3I系统外场试验中非常重要的一个环节.结合C3I系统外场试验的试验需求,建立了一套相对比较完整的、包含了C3I系统评估方法、评估指标体系和指标计算模型三要素在内的C3I系统试验评估体系.利用模糊的概念和变权评估方法,改进了传统的层次分析法,提出了一种变权模糊层次分析法作为C3I系统评估方法.最后,通过某防空情报指挥系统外场试验评估实例验证了该评估体系的正确性和科学性.所设计的C3I系统试验评估体系技术先进、科学实用,对C3I系统外场试验鉴定具有比较重要的指导意义.

新疆高校新闻专业人才培养现状、问题与对策

作为区域内新闻专业人才培养的主要阵地，新疆高校在新闻专业人才培养上起步较晚。但随着新疆区域内新闻专业人才需求的逐步扩大以及国家政策的扶持，这种状况在上世纪八十年代后得以改观。上世纪九十年代末以来，新疆部分高校相继开办了新闻专业，使新闻专业人才培养阵地迅速扩张。短期内的迅速扩张，随之也带来了诸多问题。客观理性分析产生这些问题的原因并及时寻找解决问题的对策，对提高新疆高校新闻专业人才培养质量，为区域经济发展提供人才支撑有重要意义。
